1. Apparatus for optimizing a path length of light in a particle dispersion to improve the measurement of light scattered from particles, comprising:

  • a) an optical system for illuminating a particle dispersion,b) a detection system comprising at least one detector for quantifying characteristics of light related to light scattered by at least one of said particles,c) a sample cell, comprising two optical windows, which confine said particle dispersion and pass light, from a light source, through said particle dispersion to illuminate at least one of said particles,d) means for adjusting a separation between said optical windows to change a path length of light in said sample cell, wherein said adjusting is performed by utilizing an electronic controlled actuator, ande) means for controlling said actuator based upon characteristics of light scattered from at least one of said particles.
